Industrial Truck Cable Restraint for Fast, Secure Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial trucks face challenges in securely and efficiently positioning a variable number of cables, ensuring quick and safe assembly, and reducing the risk of cable damage and fire during operation, particularly in electrically powered forklift trucks with diverse frame layouts.
Innovation Solution
The implementation of constraining elements with multiple seats and shaped entry and restraint portions for cables, which securely fasten cables in transverse directions, using elastic or slightly deformable ledges to prevent exit during operation, and are fastened to the truck frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are positioned using traditional methods in electrically powered industrial trucks, then the cables can be connected between control means and electric drives, but the cables are vulnerable to damage, cutting, or fire during operation due to imprecise or insecure positioning
Solution Approach 1:
The constraining element is divided into multiple independent seats, each capable of receiving and restraining one or more cables. This segmentation allows precise positioning of individual cables or small groups of cables, ensuring each cable is securely held in its designated position without vulnerability to damage during truck operation
Solution Approach 2:
The constraining element acts as an intermediary device between the truck frame and the cables. It provides a secure mounting structure with multiple seats that physically restrain cables, preventing them from moving into positions where they could be damaged, cut, or pose a fire hazard during operation
2Productivity
If multiple cables are positioned using traditional methods, then all necessary cables can be connected, but the assembly process is time-consuming and costly due to the need for precise positioning of each cable
Solution Approach 1:
The constraining element is divided into multiple independent seats, each capable of receiving and restraining one or more cables. This segmentation allows precise positioning of individual cables or small groups of cables, ensuring each cable is securely held in its designated position without vulnerability to damage during truck operation
Solution Approach 2:
Each seat in the constraining element is designed to accommodate multiple cables simultaneously. This multi-functional capability allows several cables to be positioned and restrained in a single operation, significantly reducing assembly time and cost while maintaining precise positioning for each cable
3Adaptability or versatility
If the cable positioning system is designed to accommodate variable numbers of cables, then different frame layouts can be supported, but the positioning system becomes more complex
Solution Approach 1:
The constraining element is divided into multiple independent seats, each capable of receiving and restraining one or more cables. This segmentation allows precise positioning of individual cables or small groups of cables, ensuring each cable is securely held in its designated position without vulnerability to damage during truck operation
Solution Approach 2:
Each seat in the constraining element is designed to accommodate multiple cables simultaneously. This multi-functional capability allows several cables to be positioned and restrained in a single operation, significantly reducing assembly time and cost while maintaining precise positioning for each cable

AI summary
An electrically powered industrial truck comprising: control means, an energy storage system (97), one or more electric drives powered by the energy storage system, a plurality of cables (13, 14, 15) to connect the control means to the one or more electric drives, a constraining element (10) suitable to constrain the position of one portion of each of the plurality of cables. The constraining element (10) comprises a plurality of seats (11, 12), each seat being suitable to receive a plurality of said cables (13, 14, 15); each seat (11, 12) being provided with: a portion of restraint (18, 19) of the cables to restrain the cables in an operational position, and a portion of entry (16, 17) of the cables to allow the entry of the cables in the restraint portion (18, 19) in a direction transverse to a longitudinal axis of the cable (13, 14, 15) during an assembly of the cables (13, 14, 15) in the seat. The entry portion (16, 17) is shaped so that it does not allow the cables (13, 14, 15) received in the restraint portion (18, 19) to exit the seat during the normal operation of the industrial truck.
